Improvement in auger



www tntc @tutti @wird Leners Patent No. 95,803, dated october 12, 1869.

IMPROVEMENT IN AUGER.

The Schedule referred to in these Letters Patent and making part of thesama.

the county of New Haven, and State of Connecticut,

have invented a new Improvement in Constructing Angers; and I do herebydeclare the following, when vtaken in connection with the accompanyingdrawing,

and the let-ters'of reference marked thereon, to be a full, clear, andexact description of the same, and which said drawing constitutes partof this specification, and represents a side view of the cutting-end ofthe auger, looking toward the edge of one of the cutters.

This invention relates to an improvement in angerbits, the object beingto combine a gouge Hoor-lip with a vertical cutter upon its extreme end.

Inordcr to the clear understanding of my invention, I will proceedtodescn'be the saine, as illustrated in the accompanying drawing.

A isthe twist of a common anger;

B, the screw-point;

C, the floor-lip npon one side', and

C', a corresponding Hoor-lip upon the opposite side.

These Hoor-lips are curvednpv from the centre, so that the cut commencesat the centre, working ontward, thus dispensing with the use of thespur-cutters.

I combine with these floor-lips, respectively, a perpendicular orside-cutter, a, rising from the iloor-1ips at their extreme ends.

These, so soon as the floor-cutters have entered 'the wood, serve totrimo and gather the chips,and prevent the binding or clogging of thecutters, whereby the auger works much easier than the gouge-lip, asheretofore constructed.

I do not wish to be understood as broadly claiming a gouge-lip auger, assuch, I am aware, is not new; but r What I do claim as my invention, anddesire to secure by Letters Patent, is

.In auger-bits, the combination of the gouge floorlips C C', with theirrespective side or vertical cutters a a, connected and arrangedsubstantially as shown and described.
